I remembered reading somewhere on here that the breathable cuban, wasn't all that bad. So, i went ahead and looked up some quotes...
"OK, I really should have posted earlier as promised so my apologies. I used this jacket on my last trip as it rained quite a bit. Performance was great and I even used it as a windshirt for most of the last day. I haven't used many breathable garments before so it would be near impossible for me to compare it to any other fabric, but it breathed well enough that I was comfortable wearing it for most of the day. There was some bushwhacking during the trip so it did suffer a bit of damage from branches and thorns but I mostly it was the thin fibers being pulled from the base material. I wish I could give more info but I am not sure what else to say other than it is definitely my "go to" rain gear at this point." ~Steven Evans
"The stuff is really quite breathable. If you put a piece of the material over a cup of boiling water the steam will come through the material quite easy and it doesn't build much condensation on the bottom side when indicates its very breathable. To me the material doesn't look like it has a film at all and feels and looks more like normal woven material." ~Lawson Kline
Hope that helps. I also remember that whoever bought up the rest of backpacking lights online stores supplies was also selling event fabric, but i'm not sure if they've sold out of it by now or not.
